What two numbers multiply to 315 and add up to 68?

Here we answer the question: "What two numbers multiply to 315 and add up to 68?"

The answer to your question is:

5 and 63

Below we illustrate and prove that 5 and 63 multiply to 315 and add up to 68:

5 × 63 = 315
5 + 63 = 68

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 68x + 315 = 0

If so, the solution to factor the quadratic equation above is:

(x + 5 ) (x + 63)

To summarize, since 5 and 63 multiply to 315 and add up 68, you know that the following is true:

x² + 68x + 315 = (x + 5 ) (x + 63)
